README.md

up

Interactively choose one of the parent dirs to change to.

Requirements & Installation

1. Install percol
2. Setup your shell to load the up function at startup

• In fish use funced up, paste contents, funcsave up
• In bash paste it in .bashrc or any other file and source it from .bashrc

Usage

Just call up and select one of the parent directories. Ctrl+C cancels.

By default, a directory containing a .env subdirectory will be selected. You may override the way the default directory is chosen by replacing the _up_test_main_dir function

up.bash

_up_test_main_dir() {
  test -d "$1/.env"
}

up() {
    local pwd="$(dirname "$(pwd)")"

    local current=0 idx=$(while [ "/" != "$pwd" ]; do
        if _up_test_main_dir "$pwd"; then
            echo $current
            break;
        fi

        current=$((current + 1))
        pwd="$(dirname "$pwd")"
    done)

    local dir=$(while [ "/" != "$pwd" ]; do
        echo $pwd
        pwd="$(dirname "$pwd")"
    done | percol --initial-index $idx)

    if [ ! -d "$dir" ]; then
        return;
    fi

    cd "$dir"
}

up.fish

function up
    set -l current 0
    set -l idx 0
    set -l pwd (dirname (pwd))

    set dirs (while [ "/" != "$pwd" ];
        echo $pwd
        if [ -d "$pwd/.env" ];
            set idx $current
        end

        set current (math $current + 1)
        set pwd (dirname "$pwd")
    end)

    for line in $dirs;
        echo $line
    end | percol --initial-index $idx | read -l dir

    if [ ! -d "$dir" ];
        return
    end;

    cd "$dir"
end
